Fluorescent molecules reveal how cancer stem cells are selectively inhibited

The study provides a clearer idea of how molecules of this type, known as ion transporters, reduce the percentage of cancer stem cells in a cell population. A team of researchers at Lund University in Sweden has developed a fluorescent variant of a molecule that inhibits cancer stem cells. Capturing images of when the molecule enters a cell has enabled the researchers, using cell-biological methods, to successfully describe how and where the molecule counteracts the cancer stem cells.

Insects also migrate using the Earth’s magnetic field

Bogong Moths on Cave Wall. A major international study led by researchers from Lund University in Sweden has proven for the first time that certain nocturnally migrating insects can explore and navigate using the Earth’s magnetic field. Until now, the ability to steer flight using an internal magnetic compass was only known in nocturnally migrating birds.

Sea urchins see with their feet

Sea urchin Sea urchins lack eyes, but can see with their tentacle-like tube feet instead, previous research has indicated. Now, researchers at Lund University in Sweden have tested their vision in a new study, and shown that while sea urchins have fairly low resolution vision - it is good enough to fulfil their basic needs.

Biodiversity increased after open sandy habitat restoration

insect Since 2012, the EU project Sandlife has worked to restore open sandy habitats in southern Sweden. Overgrown environmentally-protected areas, known as Natura 2000 areas, on sandy land in Skåne, Halland and Öland, have been opened up to become more accessible to both the public and rare plants and animals. The first results are now being presented and they are positive. The initiative has benefitted many insects, including several endangered species.

Fruit flies fear lion faeces

Fruit fly A new doctoral thesis from Lund University in Sweden shows how fruit flies use their sense of smell and humidity to find food, avoid dehydration and discover the best place to lay their eggs – in overripe marula fruits. Faeces from herbivores are also suitable, but the flies reject carnivore excrement.

Small birds almost overheat while feeding their young

Hungry birds For decades, researchers have thought that access to food determined the brood size of birds. Now, biologists at Lund University in Sweden have discovered a completely new explanation: the body temperature of small birds can increase by more than 4°C to exceed 45°C when they are feeding their young. Larger broods would require more work, resulting in even higher body temperatures - something the birds would probably not survive.

The most detailed star catalogue ever released

The catalogue is based on observations made by the European satellite Gaia, and contains the exact distances, luminosity, temperatures and colours of millions of stars in the Milky Way. Astronomers at Lund University in Sweden play a prominent part in the Gaia project.

EU agrees on a ban on the use of neonicotinoids

EU agrees on a ban on the use of neonicotinoids The European Union will ban the world’s most widely used insecticides from all fields due to the serious danger they pose to bees.

Birds migrate away from diseases

They used the results to investigate and discover major differences in the immune systems of sedentary and migratory birds. The researchers conclude that migratory species benefit from leaving tropical areas when it is time to raise their young – as moving away from diseases in the tropics enables them to survive with a less costly immune system.

How birds can detect the Earth’s magnetic field
